From a FDACS press statement:

While the Florida Department of Agriculture & Consumer Services (FDACS) is still awaiting results from product sampling (which we hope to have in the coming days), we do have results from our environmental sampling at the Big Olaf processing facility.

This will effectively shut down all operations at this processing facility, which had already been done voluntarily by the company.

Here are the test results:
